In Letters Patent grantedfto` me September 29,y

I 1868, a lubricator is shown made of a glass vessel with metallic necks. My present invention is an improvetuent upon the aforesaid lubricator, and consists in a valyeappled tothe cap,and acted upon by a spring,

so as to close the hole through which oil isintroduced after the cup lhas been filled. g

I make use of' 'a peculiarly constructed. bonnet `to i v i prevent the oil falling int'o the tube or stem, and allow `space forthecapillaryicederwhere it passess'aid bon- `net. The loil-holder, a, is contracted tothe necks b ande, and t-his is formed of glass, and set into the lower socket, d, and secured and rendered tight by a packing, e, or otherwise. Ihave shown a screw upon the I outside of the glass neck.

so as to be tight. I I

. Abovev 4the cap f is the top g, having two projections, h and z', passing through the cap f. The projection 'i acts as a valve, and the projection hhas a spiral f is the upper cap,also of metal, securedl in place spring around it, by means ot' which' the top g and valve i are drawn suiiciently tight upon the cap f,'but, by lifting the top g so as to clear the valve Ii, from its seat, thexto'p y can be turned aside, andthe lubricator filled with oil, and then the top g is to be turned back to place. I.

` This construction allows easy access to the lubricator, and prevents the risk of the top being lost ii' it were disconnected. I

The hollow stem l passes up into tbelubricator, and is provided with 'a bonnet, m, that slips over the said stem l, andtliere is a shoulder, 2, either upon the 4stem I, as in g. 1, or within the bonnet m., as in fig.

2, to prevent the bonnet being pushed too far upon the stem l, thereby the necessary space is always lel't for the capillary o, and its action is not interfered with as it would be if the bonnet pressed tightly upon said capillary o.

This capillary o is made of a wire or wires, with a covering ot' fibrous material, as in my patent of 0ctober 22, 1867. l l i By this construction the oil can be observed, the

feed of the oil will bev regular, the capillary cannot be obstructed in `its operation, the oil will not'run ont of a cup while on a loose pulley, in consequence of being I either inverted, inclined, or upright, and the quantity of oil can be seen sometimes while the pulley is being revolved; hence the same requires but little attention except Ato rellwhenthe oilis exhausted. I

The met-alsocket d lcssens the risk of the glass oilholder beingbrokcn when exposed to centrifugal action or sudden stopping or starting.

What I claim, and desire to secure by Letters Patent is I 1. The combination of the bonnet m with the shoulder 2 and stem l, substantially as and for the purposes speciiied.

A2. The spring valve i, fitted to the cap f, substan# tially as and for the purposes set forth.

3.The bonnet m and shoulder 2, in combination with the tube l, substantially as and for, the purposes set forth.

In witness whereof I have hereunto set my signature this 9th day of October, A. D. 1869.,
